Need to get the line count of a text file or document? Counting lines of any file is easy at the command line, and the command for line counting is the same in all modern Unix based operating systems, meaning this line counting trick will work the same on Mac OS and Mac OS X, Linux, BSD, and even Windows with Bash shell.

For our purposes here we will use the most direct line counting tool available at the command line, wc. The wc utility is able to display line count, as well as reveal word count and character count. Our focus here is of course on the former, so we’ll be showing how to use wc for counting lines of any text file provided as input.

If you’re an extra longtime Mac user, you might remember way back in the 1990s when desktop backgrounds on classic Mac OS versions were tiled images of various textures. This was way back when the idea of setting a single image as wallpaper was a bit extreme because it was excessively resource heavy, and so tiling a small image was the norm instead (if not using just a solid color as a background) – the good old days of computing, right?

Well, why not bring a handful of those classic Mac OS System 7 tiling wallpapers to your modern Mac?

All new iPhone models includes Siri access, the ever helpful (and sometimes goofy) virtual assistant that can perform tons of tasks by issuing simple commands by voice. But if you’re accustomed to accessing Siri by holding down a Home button and now you have a newer iPhone without a home button, like iPhone 11, iPhone 11 Pro, iPhon XS, iPhone XR, XS Max, or iPhone X, you’re probably wondering how to access Siri on the iPhone which does not have a Home button at all.

Accessing Siri on iPhone X and 11 series is easy as it ever was, it’s just different because there is no Home button on the device. It turns out there are actually a few ways to access Siri on iPhone, using a button, or by using the Hey Siri voice command.

Ever picked up iPhone XS, XR, X and found Apple Pay credit cards on screen? Or have you pulled iPhone X out of a pocket or bag and discovered that Apple Pay is open on the lock screen?

If you’re an iPhone X user who is frequently bringing up the Apple Pay screen when you don’t want to, you can disable the feature that causes Apple Pay to present itself when the side button is double-pressed. This will prevent Apple Pay from constantly coming up accidentally or unintentionally while handling iPhone X.

If you don’t want Siri to ever dictate, speak, or write out explicit language, you can disable bad language in Siri for iPhone and iPad completely.

The Notes app in iOS is ever useful and offers a great place to store whatever little tidbits of text, checklists, pictures, doodles and drawings, shared notes with other people, password locked notes, and other data points you wish to preserve in some organized manner on an iPhone or iPad. And as for storing, the Notes app on the iPhone and iPad has two different account locations for Notes data; locally on the device itself, or in iCloud.

By default with modern versions of iOS, the Notes app sets the default account save location of note data to iCloud, but if you wish to adjust the Notes default so that notes are local instead, you can do so via settings. This will impact default notes behavior, and also the default notes account that is interacted with via Siri notes requests and any Notes data visible from the widgets screens in iOS.

Upon closer inspection with Activity Monitor on the impacted Mac, you might notice that a process called “PTPCamera” is running and consuming a heavy amount of CPU usage, usually hovering around 85% or so, and it tends to persist until manual intervention has occurred.

If you regularly sleep your Mac, you may have noticed that sometimes the Mac will wake itself up and show a notification on the screen, even if the screen is locked and otherwise password protected with the login screen. These notifications that wake a Mac from sleep are called “Enhanced Notifications” and they can originate from Messages, FaceTime, social networks like Facebook and Twitter, Game Center, Back to My Mac, and Find My Mac.

Enhanced Notifications may be great for some Mac users, but others might want their Mac to sleep and stay asleep when they put their Mac to sleep, at least until they decide to wake the computer themselves.

Animoji is one of the major new software features available on iPhone XS, XR, XS Max, and X. For the unfamiliar, Animoji are animated cartoon renditions of things like a smiling pile of fecal matter, a unicorn, dog, cat, chicken, panda, pig, fox, alien, and other figures, and the Animoji feature works by using the Face ID front-facing iPhone camera to see how your face is changing and mimic those facial expressions on the animated character. You can then record little snippets of Animoji and send them to people, leading to messages that include something like a talking animated unicorn or talking animated pile of feces.

This thrilling new Animoji feature is easy to use, but it’s also easy to overlook.
